PROOF & SAFETY

An insistence on safety—
beyond global standards, to UKO’s own

Infant snaps must prevent even the risk of a child swallowing them.

UKO SNAP raises the tensile strength holding snap to fabric to an unrivaled 110N.
Surpassing Korea (50N), Japan (70N), and Europe (90N), we set a new bar for the world’s safest snap.

110N for child safety means Zero‑Defect in adult apparel too.

110N holds about 11 kg pulled straight down—snaps stay put through repeated washing and open-close cycles. Having cleared the most rigorous babywear standards, UKO SNAP delivers the same fastening quality across outdoor, casual, workwear, and every adult category.
